REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/495,015, filed on Sep. 27, 2019 and entitled COMPACT FOLDING CANE, which is a national stage application of International Patent Application No. PCT/US2018/023990, filed on Mar. 23, 2018 and entitled COMPACT FOLDING CANE, which claims the benefit of U.S. Provisional Application No. 62/476,117, filed Mar. 24, 2017, and entitled COMPACT FOLDING CANE, all of which are hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

This patent is for a compact folding cane.

BACKGROUND

Conventional folding canes include an elongated, round shaft that separates into segments with a ground engaging foot at one end, and a handle for grasping at an opposite end. Conventional folding canes like these have numerous drawbacks. For example, most conventional folding canes use round tubing for the shaft. When the conventional folding cane is in the folded-up position, the tube segments become hard to organize and are difficult to store in a tight, neat manner. In an attempt to provide minimal order, conventional folding canes often rely on an elastic strap that is difficult for users to utilize. Conventional folding canes are also inconvenient to fold-up, needing multiple steps and redundant efforts. Accordingly, there exists a need for an improved folding cane.

In some aspects, disclosed is an improved folding cane. In some examples, the folding cane can be compact, convenient to fold-up, and easy to use while being stylish, providing assistance to the user while instilling confidence. For example, the improved folding cane may be aesthetically more pleasing. In certain examples, the folding cane provides orderly storage when folded up. In various examples, the folding cane may provide the consumer or user the ability to interchange feet to improve safety, extend lifecycle of the folding cane, and to meet the demands of a given environment or use. Further, an improved folding cane may better conform to the environment in which it is used.

In various examples, a folding cane includes a handle, a tip, and at least two collapsible cane segments joining the handle to the tip. The cane segments are configurable in an unfolded configuration and a folded configuration, where, in the folded configuration, a flat or nesting surface of one of the cane segments abuts a corresponding flat or nesting surface of an adjacent cane segment.

In some examples, a collapsible cane includes a handle, a tip, at least two collapsible cane segments joining the handle to the tip, and a hinge with two parallel pivot axes between the two collapsible cane segments. The cane segments are configurable between an unfolded configuration and a folded configuration by moving the cane segments apart from one another to expose a portion of the hinge, and rotating the cane segments relative to one another about the two pivot axes.

In certain examples, a collapsible cane includes a handle, a tip, at least two collapsible cane segments joining the handle to the tip, and a connector system between the two collapsible cane segments. The connector system includes a male connector and a female connector connected by a shock cord, and the female connector includes a shock cord notch. The cane segments are configurable between an unfolded configuration and a folded configuration by moving the cane segments apart from one another to remove the male connector from the female connector, and rotating the cane segments relative to one another such that a portion of the shock cord is positioned in the shock cord notch.

In various aspects, a compact folding cane can include an ergonomically shaped handle for a comfortable and stable grip. The handle can include a built in strap that can be placed around the wrist of the user when the cane is in its unfolded position and can be used to neatly organize the cane when it is in its folded-up position. The compact folding cane optionally may also contain a shaft including at least two cane segments that can be easily separated by one motion when the compact folding cane is pulled from both directions. The cane segments each include at least one nesting surface that will enable the cane segments to store compactly and neatly when folded up. The compact folding cane can further include a foot for engaging the ground. The foot can be coupled to the shaft and easily removed by pressing a groove on the foot. The compact folding cane can come in four sizes to accommodate a full range of consumer heights without the need for height adjustment mechanisms.

Each cane segment of the compact folding cane shaft may be connected to another segment by a hinge. In certain cases, the compact folding cane can fold flat with the use of the hinges. The hinges optionally can also prevent or reduce over-extension of the cane segments. Optionally, magnets can be included with the cane segments to hold and organize the cane segments while in the folded position. The handle can optionally fold down using a similar hinge mechanism to provide additional compactness. In some examples, tension from an elastic shock-cord or other suitable flexible member can enable the handle shank to act as an over-center lock to hold the handle folded at a desired angle, including but not limited to 90 degrees. Secondary shock cords can prevent the shock cords from over extending. The wrist strap can be wrapped around the folded segments of the compact folding cane shaft and then snap into the end of the handle for additional latch security.

The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described. Directional references such as “up,” “down,” “top,” “left,” “right,” “front,” and “back,” among others are intended to refer to the orientation as illustrated and described in the description (or figures) to which the components and directions are referencing. References herein to “consisting of” may, in at least some circumstances, encompass “consisting essentially of” or “comprising.”

FIGS. 1-11C illustrate a first example of a folding cane 100. The folding cane 100 includes a handle 102, a tip 104, and at least two collapsible cane segments 106 joining the handle 102 to the tip 104. As illustrated in FIGS. 2A-B, the folding cane 100 is configurable between an unfolded configuration (FIG. 2A) and a folded configuration (FIG. 2B).

Referring to FIGS. 1, 2A-C, 3, 4, 8, and 10, the folding cane 100 includes at least two cane collapsible segments 106 but could include more as desired. For example, in FIG. 1, the folding cane 100 includes three cane segments 106A-C; however, in other examples, any desired number of cane segments may be included (e.g., two cane segments, three cane segments, four cane segments, five cane segments, etc.).

As shown in FIG. 2C, the cane segment 106 includes at least one flat or nesting surface 108, and in some cases may include more than one nesting surface 108 (e.g., two nesting surfaces 108 as illustrated in FIG. 2C, three nesting surfaces 108 as illustrated in FIG. 12C, etc.). The flat or nesting surface 108 includes a surface that is mostly flat or a surface that has radiused or otherwise non-flat corners or edges. The flat or nesting surface 108 extends along a portion of the cane segment 106. In some examples, the flat or nesting surface 108 extends along an entire length of the cane segment 106, although it need not in other examples. In various examples, the nesting surface 108 of one cane segment 106 abuts the nesting surface 108 of another cane segment 106 in the folded configuration. In some examples, the nesting surfaces 108 predefine the engagement position of adjacent cane segments 106 and optionally allows for the cane segments 106 to be self-aligning in the folded configuration. In various aspects, with the at least one nesting surface 108, each cane segment has a non-circular cross-sectional profile. In some cases, the cross-sectional profile of each cane segment includes at least one flat surface, although it need not. For example, in other embodiments, the nesting surface 108 on adjacent cane segments 106 may be complimentary in shape such that the nesting surface 108 of one cane segment 106 can abut the nesting surface 108 of the adjacent cane segment 106.

In the example of FIGS. 1-11C, a connecting system for connecting adjacent cane segments includes a hinge 110 (i.e., adjacent cane segments 106 are connected through the hinge 110). In other examples, adjacent cane segments 106 may be connected through various other mechanisms including, but not limited to, connecting systems with a male connector, female connector, and elastic band, shock or bungee cords, uni-directional hinges, multi-directional hinges, barrel-lock systems, flexible hinges with no pivot points, a connecting system with multiple pivot points, a single pivot, or various other suitable mechanisms. Similarly, the handle 102 may also be connected to a cane segment 106 (e.g., cane segment 106A) through a hinge 110. In certain cases, the connecting system allows for adjacent cane segments 106 to be movable in at least two planes. In various examples, the hinge includes two parallel pivot axes 112A-B (see FIG. 4); however, in other examples, the hinge may include a single pivot axis or more than two pivot axes. In some examples, a first portion of the hinge 110 is at a fixed position relative to one of the cane segments 106 (e.g., cane segment 106A), and a second portion of the hinge 110 is movable relative to the other cane segment 106 (e.g., cane segment 106B). In certain cases, as illustrated in FIG. 2A, a majority of the hinge 110 (e.g., the portion of the hinge 110 with the two parallel pivot axes 112A-B) is housed within adjacent segments 106 and a minor portion of the hinge 110 (e.g., a positioning ridge) remains visible in the unfolded position. In other aspects, the entire hinge 110 is optionally concealed within the segments 106 in the unfolded position, although it need not be in other examples. In certain aspects, the segments 106 are movable to the folded position by moving the cane segments 106 apart such that a portion of the hinge 110 is exposed, and then rotating the cane segments 106 relative to each other about the pivot axes 112A-B (see FIGS. 2B and 3).

In certain examples, the hinges 110 may be uni-directional (i.e., the hinges 110 can only fold in one direction) or multi-directional. In some examples, the adjacent hinges 110 (or hinges at opposing ends of a cane segment 106) are interconnected through an elastic member 114 (e.g., shock cords) or other suitable members that allow for movement of the cane segments 106 between the folded and unfolded configurations. In such cases, the hinge 110 may include a slot or other suitable feature for connecting the hinge 110 to the elastic member 114 (see, e.g., FIGS. 4 and 8). In some optional examples, a lower-most cane segment 106 (e.g., cane segment 106C) includes a foot anchoring member 120 and the handle 102 includes a handle anchoring member 122 (see FIG. 9). In such examples, the system of hinges 110 and elastic members 114 extends from the foot anchoring member 120 to the handle anchoring member 122.

Optionally, as illustrated in FIGS. 4 and 8, a secondary elastic member 116 may be provided to prevent over-extension of the elastic member 114. In other optional examples as illustrated in FIG. 10, a locking collar 136 that is attachable to an end of one of the cane segments 106 includes one or more locking tabs 138 that are configured to engage corresponding grooves 140 of the hinge 110 (or vice versa). Optionally, adjacent cane segments 106 may include magnets 118 (see, e.g., FIG. 4). In the folded configuration, the magnets 118 of the adjacent cane segments 106 are configured to interact and aid in retaining the cane segments 106 in the folded configuration.

Referring to FIGS. 1, 2A-B, 3, and 9, in various aspects, the handle 102 is ergonomically shaped for a comfortable and stable grip. In certain examples, the handle 102 is connected to the top-most cane segment 106 (e.g., cane segment 106A) through a hinged portion 130 of the handle anchoring member 122 such that the handle 102 can be folded relative to the top-most cane segment 106 (see, e.g., FIG. 2B). Referring to FIGS. 11A-C, in some optional examples, in addition to being foldable, the handle 102 may also be rotatable relative to the top-most cane segment 106. In such examples, the top-most cane segment 106 may include a tab 134 and groove 132 that predefine rotation positions of the handle 102. In other examples, a profile of the cane segment 106 may limit the amount of handle rotation.

As illustrated in FIG. 9, in certain cases, the handle 102 optionally includes a top shell 121 and a bottom shell 123. Optionally, an overmold 124 is provided on the top shell 121. In some optional examples, the handle 102 includes a strap 126 that can be placed around the wrist of the user when the cane 100 is in its unfolded configuration. The strap 126 may optionally be used to organize and retain the segments 106 of the cane 100 when the cane 100 is in its folded configuration. In certain examples, the handle 102 accommodates one or more accessory modules 128 that are removable and replaceable as desired by the user. In some aspects, the accessory module 128 includes, but is not limited to, a flashlight, fitness tracker, GPS finder, music player, release button, sensor, or various other accessory modules as desired.

Referring to FIGS. 1, 2A-B, 3, 4, 5, and 7A-B, the tip 104 includes a removable foot 142. In certain aspects, the foot anchoring member 120 includes at least one slot 144 that is configured to selectively engage and secure the foot 142 on the cane segment. In some examples, the foot 142 is a self-standing foot 142 that is “X” shaped (or having any other suitable shape) such that the folding cane 100 stands upright on flat ground. In addition to being self-standing, in some examples, the foot 142 may be used as a step-lever to upright the folding cane 100 if the cane 100 has fallen on the ground (see FIG. 7B). Optionally, and as illustrated in FIG. 7A, the foot 142 may include a rigid material 146 and a flexible material 148. Optionally, the rigid material 146 forms the core of the foot 142 and the flexible material 148 forms the grip of the foot 142, although it need not. In other examples, as illustrated in FIG. 6, the foot 142 is a single tip foot 142.

As illustrated in FIGS. 5 and 6, in some examples, the foot 142 includes a groove 150. In certain cases, the groove 150 may be utilized as a button to aid in removal of the foot 142 from the folding cane 100 (e.g., to replace the type of foot 142 on the folding cane 100). In various aspects, the groove 150 receives a portion of one of the cane segments 106 in the folded configuration such that the foot 142 nests with the collapsible cane segment 106. For example, FIG. 2B illustrates the foot 142 nested with the cane segment 106B.

FIGS. 12A-16 illustrate another example of a folding cane 1200. In some examples, the folding cane 1200 may be similar to the folding cane 100. In some aspects, compared to the cane segment 106 of the folding cane 100, the cane segment 106 of the folding cane 1200 has a different profile. For example, as illustrated in FIG. 12C, the cane segment 106 of the cane 1200 has a triangular profile and includes three nesting surfaces 108.

In various cases, instead of the hinges 110, the folding cane 1200 includes a connecting system 1252 between adjacent cane segments 106. Compared to the connecting system of the folding cane 100, the connecting system 1252 includes a male connector 1254 and a female connector 1256 connected by a shock cord 1258 (or other suitable member). As best illustrated in FIGS. 14A-C, the female connector 1256 includes at least one shock cord notch 1260. In the folded configuration, a portion of the shock cord 1258 is positionable within the shock cord notch 1260. In some examples, the male connector 1254 includes a ridge 1262, and, in the unfolded configuration, the ridge 1262 is retained in the shock cord notch 1260.

As illustrated in FIGS. 13B-C, compared to the handle 102 of the folding cane 100, the handle 102 of the folding cane 1200 is rotatable about an axis of at least one of the cane segments 106. It will be appreciated that when the folded cane 1200 (or folding cane 100) is in the unfolded configuration, the axes of the cane segments 106 align. In the cane 1200, the accessory module 128 is a release button (see FIG. 16); however in other examples, additional and/or different accessory modules 128 may be utilized with the handle 102.

FIGS. 17A-22C illustrate another example of a folding cane 1700. Compared to the folding cane 100, the connecting system of the folding cane 1700 includes hinges 110 that are uni-directional. In addition, compared to the folding cane 100, the hinges 110 of the folding cane 1700 are not concealed within one or more of the cane segments 106 in the unfolded configuration. Optionally, a barrel lock comprising at least one barrel 1766 and a flexible cord 1768 connects the handle 102 to each hinge 110. As illustrated in FIG. 22A, in the folded configuration, the barrels 1766 are positioned within the respective cane segments 106. In FIG. 22B, the cane 1700 is in the unfolded configuration and the barrels 1766 are in an unlocked position (i.e., they are offset from the center 1770 of the hinges 110 (not shown) such that the cane segments 106 can be folded). In FIG. 22C, the cane 1700 is in the unfolded configuration and the barrels 1766 are in a locked position (i.e., they overlap the center 1770 of the hinges 110 (not shown) such that the cane segments 106 cannot be folded). In some examples, compared to the handle 102 of the folding cane 100, the handle 102 of the folding cane 1700 defines a handle cavity 1764 that receives a portion of the cane segment 106A in the folded configuration (see, e.g., FIGS. 19A-B).

FIGS. 23A-B illustrate another example of a connecting system for joining adjacent cane segments 106 (although only one cane segment 106 is illustrated in the figures). As illustrated, the connecting system includes a flexible hinge 2310 with no pivot points; instead, a shape and material forming the flexible hinge 2310 allows for the flexible hinge 2310 (and thus the cane segments 106) to be foldable in at least two planes. In the example of FIGS. 23A-B, the flexible hinge 2310 is foldable in a single direction.

FIGS. 24A-B illustrate another example of a connecting system for joining adjacent cane segments 106. As illustrated, the connecting system includes a flexible hinge 2410 with no pivot points that is similar to the flexible hinge 2310. Compared to the flexible hinge 2310, the flexible hinge 2410 is optionally foldable in two opposing directions from the unfolded position (see arrows 2401A-B) but not in perpendicular directions (see arrow 2403). As a non-limiting example, the flexible hinge 2410 is foldable side-to-side, but not front-to-back (or vice versa).
